OK something similar on one of my minis...I put a tennis ball in area below fetlock and above hoof to fit into that curve, vetwrapped it and it kept the foot out. Wrapped above fetlock several inches & around hoof for a while. While it was like a stiff joint there, it kept foot in position & from wearing the skin off of the ankle and up above hoof. His was cut inside the leg, above the hock around & below. Two places became one and it took a while to heal. Couldn't stitch.. would have ripped out from tension to walk. Took a couple months to heal that cut but never was able to correctly use the lower joint to hold foot in position. So I made him a support to keep foot in line. He adapted well. Same leg as your doe!
We did all the xrays, ultrasounds, seemed it would begin to work again.....but, all else healed & you would never have known it!! Never an infection but, the fluids that didn't drain from the cut, ran down the tissue & out at the hoof corona edge....watch for that pressure release, in case. A lot of hosing, bandaging, a fantastic herbal spray, pain & ulcer prevention meds. A lot of work.
I hope your girl does well. Don't mean to be the bearer of bad news but you have some extra work there. It helps that she is smaller. You may be able to use a roll of cloth as smaller hoof/joint, vice a ball. LOL Just a thought for keeping as much working right as possible.
